MANIFOLD DUPLICATING DEVICE.

SPECIFICATION forming part of Letters Patent N0.`7O97,853, datedSeptember 23, 1902.

Application filed March 31, 1902.

. full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, which form apart of this speci- Iication.

My invention has for its object a manifold duplicating device; and itconsists of the construction hereinafter described and claimed,

. and illustrated in the accompanying drawings, in which- Figure l is aview in perspective, showing the device in open position. Fig. 2 is aplan view of the same. Fig. 3 is an end view; and Fig. 4 is a view insection on the line 4 4, Fig. 2. Fig. 5 illustrates a modification.

More particularly iny invention is intended to provide a device of thischaracter whereby duplicate copies of original drafts, checks, notes,letters, and other original documents can be rapidly secured by use of acarbonsheet without the necessity of removing the carbon-sheet each timethat the sheet written uponis removed and without the necessity ofinsertion of the hand between the sheets to be used. v

My purpose is to provide a simple and compact device of this nature ofsuperior efticiency and utility.

As is well known, a usual method of making duplicate copies has been toinsert by hand a loose carbon-sheet between the upper and lower sheetsand after the copy is made then to remove the duplicate sheets, take outthe carbon-sheet and insert it between the next two sheets. By my devicelthe carbon-sheet .is not required to be touched or replaced in makingdiierent duplicate copies.

I carry out my invention as follows:

In the drawings, a denotes a base, and b a cover therefor, the coverbeing preferably reversible to fold either side uppermost when open orclosed and to this end is shown connected with the base by swinging armsc c,

jointedly connected with the cover, toward Serial No. 100.794. (Nomodel.)

the longitudinal center thereof, and with the base, as shown, as by earsd and e. Toward one edge of the base is located a revolving shaft orrollerf, which may be suitably journaled to the base in any propermanner, as in bearings or brackets g. This revolving shaft may beslitted, as indicated at h, to hold one end of a continuous sheet ofvany desired length rolled thereupon. Any desired means may be providedto clamp or hold the carbonsheet upon the roller. The shaft or roller isprovided at its extremities with means to operate the same, as withheads t', to facilitate the rolling or unrolling of the carbon-sheetthereupon. Upon this base a, is secured the blanks, (indicated atj,)which may either be padded or bound or which may be loose or perforated.The base a is shown with posts 7c, upon which the blanks may be secured,said posts preferably formed with sharp edges, (indicated at Z,) so thatthe blanks can be more easily torn away therefrom. Over the block ofblanks j is also preferably located a pressure-plate, (indicated at m,)said plate being located upon the posts la. Springs 'n are alsopreferably employed, bearing upon the extremities of said plate, saidsprings being preferably fulcrumed, as indicated at p, so that they canbe swung out of the way or off from the pressure-plate, as indicated inthe dotted line in Fig. 4. The carbon-sheet q is drawn outwardunderneath the pressure-plate and over the block of blanks j. Upon onesurface of the cover is engaged in any suitable manner a series ofblanks (indicated at 13) the blanks being secured to the cover in anydesired manner. If a block of blanks is employed, the lower cardboardbase of the block may be secured underneath a loop or pocket s, whichwill serve to hold the blanks fr in place.

When it is desired to make a duplicate copy,

one of the blanks 1' is detached and placed over the carbon-sheet q,which lies above the blanksj. The blank r may then be written upon, acarbon-copy being made thereby upon the upper sheet of the blanksj. Inplacing the sheet r upon the carbon-sheet it may be guided by placingits upper edge against the pressure-plate, thereby bringing the printedblank r im mediately overthe duplicate blanks j, lying under thecarbon-sheet. The pressure-plate when the springs exert their ten- IOOsion thereuponwillhold the duplicatingsheets and carbon in place. Theedge of the pressure-plate will also serve as a straight edge to aid intearing off the carbon-sheet when it has become Worn. Obviously whenevera portion of the continuous carbon-sheet has been used up its ends maybe torn on and the sheet nnrolled from the roller The coverplate is alsopreferably provided with a bracket or flange t to prevent the blanks 1'from falling out when the cover is reversed and closed down over thebase and over the blanksj and carbon-sheetq. When the duplicate sheetsare exhausted, lthey can obviously be conveniently replaced, the blanksjbeing inserted in place by removing the pressureplate. When the carbonstrip has been entirely exhausted, a new strip can be readily securedupon the roller.

The device, it will be seen, is adapted for making duplicate copies ofdeposit-slips, drafts, checks, notes, and letters used chiey by banks,as well as for miscellaneous corre spondence, sale-slips, tbc.

The operation of the device is obviously simple and convenient..

In the operation of the device an absolute facsimile is obtained and aconsiderable saving in time is also effected.

I do not limit myself to any particular means for holding the blanks inplace. lVhen a duplicate copy has been made, the sheet underneath thecarbon is detached, leaving the carbon in place for the next duplicatecopy. The carbon-sheet may be unrolled, so

as to leave sufficient marginal blanks to be readily engaged by the handof the operator` to detach the blanks without touching the carbon. Thecarbon is thus self-adjustable.

I do not limit myself to the employment of a hinged cover, inasmuch asthe base might be extended to form a support for the blanks, as shown inFig. 5, within the scope of my invention. The cover when in unfoldedposition constitutes practically an extension of the base, and Icontemplate an extension of the base to hold the blanks 0^ with orwithout said extension being hinged to the base.

IVhat I claim as my invention isl. In a duplicating device, a base,provided with a revoluble carbon-roller, means to secure a series ofblanks upon the base, a pressure-plate, and springs having a removableengagement upon said plate.

2. In a duplicating device, a base, brackets upon said base, a revolublecarbon-roller carried by said brackets, means for holding a block ofblanks upon said base, a reversible cover provided with arms pivotallyengaged at their extremities with said brackets, and with the coverintermediate the longitudinal marginal edges thereof whereby the covermay fold either side uppermost when opened or closed, and means to holda separate block of blanks upon said cover.

In testimony whereof I sign this specification in the presence of twowitnesses.
